This pilot study aims to compare the aesthetic outcome of patients receiving one single-unit implant restoration in the aesthetic zone with zirconia and titanium abutments by means of three of the aesthetic indexes proposed in the literature (PES/WES, ICAI and CIS), in order to understand if there is a correlation between them, as well as which of the abutments has a better aesthetic outcome. The participants (n=16) were submitted to a control visit, in which photographs were taken, a radiograph was collected and information regarding clinical aspects was obtained. The photographs were analysed by 19 external observers and one of the investigators. The correlation between indexes was calculated by the use of the Cohen's k and the internal consistency of the indexes was analysed by the Cronbach's α. There is an accordance between the absolute scores of the indexes, but there is no correlation when the cut-points, that discriminate an aesthetic from an unaesthetic outcome, are employed [PES/WES vs. ICAI (k=0.13)]. Before the same case, the ICAI has a 2.25 (1.96-2.59, 95% CI) higher risk to assign an unaesthetic outcome than the PES/WES. The PES/WES index has the higher internal consistency value (Cronbach's α=0.85). The cases with zirconia abutments were assessed as being more aesthetic than the ones with titanium abutments (p AID - 857434
